Bug #1262: Heap Corruption in DL::Handle

• Status: Closed
• Assignee: -
• Target version: 1.9.1
• ruby -v: ruby 1.9.2dev (2009-03-06) [i386-mswin32_90]

=begin
The test case below on Window, when running with -RCT1, reveals heap corruption. The problem is that gettimeofday is defined in the c library on windows, so the function is never found. That causes handle.c to incorrectly deallocate a buffer which it then writes to. Patch is attached.

Hmm, gettimeofday is not defined, which reveals the bug.
